The breaking, possibly due to Higgs VEV, generates a mass gap μ in the unparticle continuous mass spectrum. This effect is incorporated into the unparticle propagator in a way that renders smooth transition to a massive particle propagator as unparticle dimension approach one. We concentrate especially in the most likely case μ ≈ MZ and Z μ > M and discuss in muon pair production how to distinguish the original unparticle and the unparticle with mass gap μ.連續質量粒子尺度不變標準模型UnparticlesScale InvarianceBanks-ZakesGeorgiMuon Pair ProductionSM
